I have mealies available at all times. I put crickets in with only some of my Leos, some of my Leos won't eat crickets so I don't put any in with them. I feed one or two waxworms per Leo per week for a treat. It's been a wonderful bonding experience as I've been hand feeding and now my Leos seem a lot more excited to see me. Makes me feel a little guilty on the non wax worm days when they come up and stare at me with those big eyes wondering why I'm not getting them their treats. I wish there was something more healthy that they'd like just as much for a treat and some variety. I might try superworms now that they are getting bigger. I've seen silkworms and butterworms for sale but don't know how they are for adding variety.
As for crickets being stinky and noisy, I buy the smaller ones that don't make noise, and if you put them in a large tub and clean it at least once a week there really is no smell. If they are in too small of a container or are overcrowded or if you don't ever clean the container, then yes they will smell.
I will admit I am afraid of crickets right now after the recent postings. I buy mine from the pet store and know there is no mold in the tubs there, but don't know about the conditions where they were before the store. There is no mold in my cricket tubs that I've ever seen. I use that calcium enriched yellow cricket jell for watering the crickets.
